PSY 335 Interpreting Statistics Worksheet Guidelines and Rubric
In order for psychologists to conduct effective assessments, they must interpret test data. This assignment provides you an opportunity to analyze two sets of data and practice interpreting them. This assignment is intended as a review of descriptive statistics and correlation—a refresher to set the stage for understanding how these concepts will be applied in future modules, to understand what the scores represent, and to be able to summarize the data in a meaningful way. Assessment and Testing Paper
Prompt: The included data set contains two sets of data—Verbal IQ test scores and Reading test scores, along with descriptive statistics for each variable and correlation data comparing the two variables. Please answer the following questions in the space provided in the Interpreting Statistics Worksheet.
In the Interpreting Statistics Worksheet, the following critical elements, specifically, must be addressed:
I. Using the provided data and graphs, describe the frequency distribution for the IQ test: a) What is a typical score for this sample? b) How variable are the scores? c) How are the scores distributed?
II. Using the provided data and graphs, describe the frequency distribution of the reading test scores: a) What is a typical score for this sample? b) How variable are the scores? c) How are the scores distributed?
III. Consider the correlation data given the provided data and graph: a) How are IQ and reading achievement related?
IV. Evaluate the data from a psychological testing perspective. a) Are these samples good representations of the general population? How do you know? b) What could you do to make them a more representative sample? c) How would you interpret the correlation results? d) What are some ways this knowledge of their relationship could be used?
